Always used to DAZ Loader, i'm bit confused about differences in terms of performance. Could Windows Loader be viewed as an automation of the SLP OEM process described which give exactly the same results?
Daz loader checks first if a valid slic exists inside the bios. If it exists it applies the corresponding certificate + key. If there is no valid slic inside the bios, the loader part will be installed to emulate an oem bios with slic, and it applies the corresponding certificate + key.
The BBBBB key is not a real one, it is a placeholder shown if the key has been removed from the Registry (via "slmgr.vbs /cpkey"), or in case of MAK (which is never stored in the Registry).
